var=var2?

trying to make this simple script but I get a bad function A10 on output. I also don't know how to use the =.

(reninsatt "A10" "new block NEW LOGO" "Template_New_2010")

(defun reninsatt(oud new filename/)
  (progn
 	(command "-rename" "b" oud new)
 	(command "_.-insert" new = filename "y" nil)
(command "_.attsync" "n" new)
     )
 (princ)
)

I don't think you can insert blocks that exist in another file, with the INSERT command. You can only insert the file itself.

I don't know about in LISP but in script it is

ExistBlockName=NewBlockName

to redefine the existing block to the definition in an external dwg file. Note that there are no spaces.

yes, it inserts a file (exported wblock) but it inserts it as the name before the = so it replaces an old block which I want.
